An oxide that forms an acid when added to water; soluble nonmetal oxides are acidic anhydrides. (Section 22.5)

A reaction in which a reagent adds to the two carbon atoms of a carbon–carbon multiple bond. (Section 24.3)

An organic compound that has an NR2 group attached to a carbonyl. (Section 24.4)

A rule that determines the order in which orbitals are filled by electrons. Specifically, the lowest energy orbital is filled first.

The amount of energy required to break a bond into two radicals in the gas phase at 25°C, A!B !> A• 1 •B

The distance between the centers of two bonded atoms. (Section 8.3)

Covalent hydrides of boron. (Section 22.11)

A compound containing a Br group and a hydroxyl group (OH) on adjacent carbon atoms.

A tetrahedral carbon atom bearing four different groups.

In electrocyclicreactions, a type of rotation in which the orbitalsbeing used to form the new s bond must rotate in opposite directions (one rotates clockwise while the other rotates counterclockwise).

A technique for separating amino acids from each other based on a difference in pI values.

Cleavage of a bond so that each fragment retains one electron; formation of radicals.

For an amino acid, the specific pH at which the concentration of the zwitterionic form reaches its maximum value.

A substance that exhibits one or more partially ordered liquid phases above the melting point of the solid form. By contrast, in nonliquid crystalline substances the liquid phase that forms upon melting is completely unordered. (Section 11.7)

A spherical arrangement of organic molecules in water solution clustered so that their hydrophobic parts are buried inside the sphere and their hydrophilic parts are on the surface of the sphere and in contact with water

The number of molecules that participate as reactants in an elementary reaction. (Section 14.6)

The smallest increment (a quantum) of radiant energy; a photon of light with frequency n has an energy equal to hn. (Section 6.2)

A triglyceride having several carbon-carbon double bonds in the hydrocarbon chains of its three fatty acids.

A Michaelreaction in which an enamine functions as anucleophile.

An excellent leaving group (OTs). transition state (Sect. 6.6): A state through which a reaction passes. On an energy diagram, a transition state corresponds with a local maximum.
